Chris Brown’s lawyer Mark Geragos has officially filed a legal response to accusations that his client lied.

The R&B singer visited court Wednesday with Rihanna close at his side following prosecutors’ accusations that he submitted fraudulent documents supporting his community service hours.

Although the star received confirmation from police officials that he finished his service days, the Los Angeles District Attorney’s office filed papers claiming that these supporting documents are fraudulent.

TMZ reports that Mark has submitted an official reply with what he claims to be irrefutable evidence that Chris did in fact complete his required 180 days of community service.

The papers dispute the DA’s assertion that "no human being ever witnessed" the star working. According to Mark the city of Richmond’s deputy chief of police “observed Brown working very hard at cleaning the brush at the [police] stables."

Part of the filing includes cheques worth over $31,000 paid to the Richmond Police Department for a security detail that Chris used while he was in the state of Virginia to volunteer his time.

Mark assures that his client is in that right as according to documents he believes, “what we've uncovered so far should shock the conscience of the court. And this is only the tip of the iceberg."

Chris is currently under a five-year probation for his 2009 assault on then-girlfriend Rihanna.

On September 14 2012, Chief of Police in Richmond, Virginia Bryan T. Norwood wrote a letter to the court saying the crooner successfully completed 220 days of work. Apparently he laboured at Tappahannock Children's Centre, a charitable organisation where Chris’ mother was once director.

The Richmond Police Department admits that they only supervised Chris’ service on at most 10 occasions.
